Bile acid profile and decrement rate of serum total bilirubin after biliary drainage.
Non-esterified (non-sulfated and non-glucuronidated) bile acid profile in the serum and bile was assessed using mass fragmentation spectrometry in relation to the decrement rate of the serum total bilirubin after relief of the biliary obstruction by external biliary drainage in fourteen patients. Biliary excretion of the total bile acid was decreased and the serum ratio of cholic to cenodeoxycholic acid was low in the patients with refractory jaundice. An unusual bile acid, 3 beta,7 alpha-dihydroxy-5 beta-cholan-24-oic acid, was detected in the sera of all patients early after biliary drainage. Disappearance of this bile acid from the serum was delayed in refractory jaundice. These findings suggested that extremely prolonged jaundice after biliary drainage resulted from profound liver cell damage secondary to biliary obstruction.
